MOP-WRINGER.

SPECIFICATION forming part of Letters Patent No. 560,189, dated May 19,1896. A pli ati fil d February 12, 1895. Serial N0. 538,134. (No model.)

T aZZ whmn it may concern.-

Be it known that I, ARTHUR M. BURNHAM, a citizen of the United States,residing at Gardiner, in the county of Kennebec and State of Maine, haveinvented a new and useful Improvement in MopJVringers, of which thefollowing is a specification.

My invention relates to combined mopwringers and pails; and it consistsin certain novel features of construction whereby a more economical,durable, and effective device is produced, as will be hereinafter fullydescribed, and particularly pointed in the claims.

Referring to the accompanying drawings, forming part of thisspecification, Figure 1 is a side elevation of my improved mop-wringerand pail. Fig. 2 is a similar view of the opposite side of the same.Fig. 3 is a plan view of the same. Fig. 4 is a vertical transversesection, on an enlarged scale, taken on the line a I of Figs. 2 and 3.Fig. 5 is a vertical longitudinal section taken on the line 5 5 of Figs.and l.

1 represents the pail, which is preferably of galvanized sheet metal andwhich constitutes the main support for the operating parts of themop-wringer. The pail carries a roller 2, which I term the stationaryroller.

is the moving roller, which is trunnioned at 1 in its supporting-frame5, which is in turn attached at G to the corresponding arms of the mainoperating-lever '7. 7

The lever 1 is fulcrumed at 8 upon Y- shaped frames 9, which are rivetedto opposite sides of the pail at 10 and have downwardly-extending ears11, to which are secured at 12 the feet 13, which project forward, as at1%, to form the base upon which is depressed the pedal 15, secured tothe front end of the main operatinglever 7. The legs 1-3 are furthersecured to the bail-ears 16 by a transverse strap 17,which projectsacross the under side of the front of the pail, as shown in Fig. 1.\Vhen the pedal is depressed to bring the removable roller 3 against thestationary roller 2, it will be observed that the pressure from the footafter the roller 3 comes to a stop is exerted downward through theframes 9 and transmitted to the feet 13, and thus the thin metal formingthe walls of the pail is relieved of a force which would soon destroythem if lever 7 were fulcrumed directly on the pail.

18 represents a foot which may be centrally disposed beneath the rear ofthe pail and serve, in connection with the two forward]y-projecting feet13, to support the device in proper position. To sustain the main lever7, which is in the form of a bell-crank lever, it is trussed by bars 19,which extend between the two arms of said lever on opposite sides of itsfulcrums.

Referring nowto Figs. 3, 4c, and 5 it will be seen that the stationaryroller 2 is trunnioned at 20 in a bracket 21, which is in turn supportedupon a shaft 23 at the ends thereof and held with its roller 2 in normalposition, and adapted to oppose with a yielding force pressure of themovable roller 3 by reason of coil-springs 24, which are mounted uponthe shaft 23, and which have one end bearing against the pail at 25,while their other ends bear at 26 against the bracket 21. By this meansthe roller 2 is adapted to yield against an excessive pressure of themovable roller 3 and thus avoid excessive strain on the parts. Theroller 3 has sufficient play toward the front of the pail to permit thepedal 15 to reach the forwardly-extending legs 13 before said roller 3reaches its final limit of movement, even when a mop of ordinary bulk isbeing squeezed between the rollers. Obviouslyas the pedal 13 reaches thelegs 15 further movement cannot take place, and the pressure thenexerted upon the mop becomes that which is imposed by the resistance ofsprings 21, and which can always be made of sufficient strength toimpart all necessary pressure to remove surplus water from the mop. Inmounting the shaft 23 in the pail I prefer to employapair ofbearing-plates 27 on opposite inner sides of the pail, which plates 27are bored to permit the passage of shaft 23,which may then be secured inplace in any suitable wayas, for instance, by nuts 28. In addition toperforming this function plates 27 are likewise provided with extensions29, which are bent at the corners of the plate, as shown, and inaddition to thus making angular braces for the vessel afford bearingsfor the ends 25 of the springs 21. In addition to the wringing-rollers Iemploy a pair of hinged and au- IOO to'matically operating collectingarms 30, preferably formed of steel wire bent into a suitable shape, andformed at their ends with eyes 31, which receive vertical pins32,mounted in a supporting-bracket 33, whereby said arms are adapted toswing toward and away from each other to gather the fibers of the moptogether in the act of wringing, but to offer no obstruction to theinsertion of the mop in the pail when the rollers are separated. Inorder to thus operate the collecting-arms toward and away from eachother simultan eously with the approach and separation of the rollers,each arm has an extension 3at,which projects into the slot of acrank-lever 36, which is in turn carried by a shaft 37, having bearingat 38 within the pail and projecting at 39 through the plate. This shaft37 carries on its outer end a rockarm 40, which is connected by a pitman5L1 with the main operating-lever 7 at a point i? suiiiciently distantfrom the fulcrum of the lever to impart the necessary movement to therock-arm to cause the lever 36 to operate the arm's SO in the mannerabove described. The movement of these operating parts, and consequentlyof the arms, is positive in both directions. The main operating-lever,however, is provided on one side with a controlling C-spring 43, whichis anchored at M and has controlling connection at 15 with said lever 7.The spring 13 is secured at 44; to one of the frames 9, pref erably bythe attaching-screw 12, which has been referred to. If desired, thewear-plate 46 maybe attached to the front of the pail in order toreceive the impact of the pedal 15, which serves as the stop forlimiting the rearward movement of the main lever and the roller which itcarries.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. In a combined pail and mop-wringer the combination of the pail, therollers, and the lever for controlling pressure between the same thegathering-arms 30 mounted on suitable shafts 32 and having the extendedends 3% by which they may be controlled, and the means for positivelymoving the gatheringarms 30, consisting of the crank-ar1n 36 in whichthe ends Sat have bearing, a rock-shaft 37 carrying said crauk-arm and acrank 40 connected through the medium of the pitm an etl with the mainoperating-lever, all substantially as and for the purposes set forth.

2. In a mop-wringer, the combination of a pail, a roller journaled insaid pail, a pair of frames, secured to the sides of the pail, a pair ofsupports pivoted to the pail and connected with the said frames, a pairof operating-levers fulcrumed to the frames having a roller journaled atone end and a pedal at the other, a pair of gathering-arms mountedwithin the pail, and asuitable connection between the saidgathering-arms and the operating-levers substantially as shown anddescribed.
